Python Programming

Lists and tuples are standard Python data types that store values in a sequence. Sets are another standard Python data type that also store values. The major difference is that sets, unlike lists or tuples, cannot have multiple occurrences of the same element and store unordered values. What does set () do in Python? set() method is used to convert any of the iterable to sequence of iterable elements with distinct elements, commonly called Set. Parameters : Any iterable sequence like list, tuple or dictionary. Returns : An empty set if no element is passed. Non-repeating element iterable modified as passed as argument.

# calculate average weight wlist=[] for i in range(0,500): mes="Input your weight (0 exit): "+str(i)+" " w=input(mes) iw=int(w) if iw==0: break wlist.append(iw) print(wlist) print("input number = %d " % len(wlist)) print("sum = %d average = %d " %(sum(wlist) , sum(wlist)/len(wlist))) 補足：体重の値に０が入力されるまで、５００人以下なら何人でも体重の値を受け付け、 その平均値を求めます。

>>> >>> len([1,2,3]) 3 >>> [1,2,3]+[4,5,6] [1, 2, 3, 4, 5, 6] >>> ["hello! "]*3 ['hello! ', 'hello! ', 'hello! '] >>> 3 in [1,2,3] True >>> max([1,2,3,4]) 4 >>> min([1,2,3]) 1 >>> list((1,2,3)) #converts a tuple into list [1, 2, 3] >>> for x in [10,20,30]: print(x) 10 20 30 >>>

What is sequence a particular order in which related events, movements, or things follow each other. a set of related events, movements, or things that follow each other in a particular order. what are 6 built-in types of sequence in python In this Python Sequence Tutorial, we will discuss 6 types of Sequence: String, list, tuples, Byte sequences, byte array, and range object. What are sequence types in Python? There are seven sequence types: strings, Unicode strings, lists, tuples, bytearrays, buffers, and xrange objects. Dictionaries and sets are containers for sequential data. See the official python documentation on sequences: What are the sequence data types? Sequences allow you to store multiple values in an organized and efficient fashion. There are several sequence types: strings, Unicode strings, lists, tuples, bytearrays, and range objects. Dictionaries and sets are containers for non-sequential data. Enable Ginger Cannot connect to Ginger Check your in...

Like any other GUI module it also supports images i.e you can use images in the application to make it more attractive. Image can be added with the help of  PhotoImage()  method. This is a Tkinter method which means you don’t have to import any other module in order to use it. Important:  If both image and text are given on  Button , the text will be dominated and only image will appear on the Button. But if you want to show both...
